Mohamed Amine Benyakoub

1. check all boundary conditions.

2.Materials that dont have plastic behavior cannot have any failure, so the strength reduction calculation will never converge.

3.Apply the SSR on all materials that are supposed to fail.

Good luck

Eeswara Sai Chaitanya Kumar Rudra

try clean geometry

Nurmalita Meivanesa

sir I find it, if u do all things that what mr Mohamed said and still fail, then check the field stress according to the situation, if you near the the surface then use gravity, but if ur excavation is too deep then use constant. hope this usefully thanks
